Abstract: A method and a device for winding a spun yarn body from an inside wall of a spinning centrifuge of a pot spinning machine onto a tube (10) introduced for such purpose into the spinning centrifuge. The yarn extending between a yarn guide tube (6) and the inside wall of the spinning centrifuge is caught by lowering the tube past the mouth of the yarn guide tube and the winding process initiated. A remnant of spinning yarn is created thereby between the draw frame and the tube foot. In order to avoid disturbances due to the free end of this remnant of spinning yarn, the remnant of spinning yarn is separated from the yarn body and the tube and subsequently removed by suction.

Abstract: To secure the end of the roving (5) to packages (9) before their doffing from a roving frame, it is proposed to initially raise the package support carriage (2) into a position such that the lower end (4a) of the tubes (4) is at the level of the compressor (16) of the flyers (6), then rotate the packages (9) and flyers (6) through a few revolutions in order to wind and secure the roving (5) onto the lower end portion (4a) of the tubes (4), after which the carriage (2) is lowered to break the roving (5) in the section between the lower end (4a) of the tubes (4) and the flyers (6). Preferably, before lowering the packages (9), a reserve of roving (5) is created by slowly rotating the flyers (6) and packages (9) through a few revolutions, to simultaneously twist the roving (5) and strengthen it.

Abstract: When a full bobbin signal from a counter CCM counting the number of rotations of the front roller (3) is output, the control element (28) outputs a signal directed to the control motor (M2) of a unit (29) for reciprocating a bobbin rail (10). As a result, the rotation of the control motor (M2) is combined with the rotation of a differential gear (14 ) connected to the main motor (M1), so that a reciprocating movement of the bobbin rail (10) after the full bobbin state is obtained which is faster than that obtained during a usual taking up operation of the roving, which causes the roving to be wound on the bobbin in a much coarser state than usual. A limit switch (LSP) detects a predetermined desired position of the bobbin rail (10), and the control element (28) outputs a signal directed to the unit (29), whereby the main motor (M1) and the control motor (M2) are stopped.

Abstract: An electrically programmable antifuse element incorporates a composite interlayer of dielectric material and amorphous silicon interposed between two electrodes. The lower electrode may be formed from a refractory metal such as tungsten. Preferably, a thin layer of titanium is deposited over the tungsten layer and its surface is then oxidized to form a thin layer of titanium oxide which serves as the dielectric material of the composite dielectric/amorphous silicon interlayer. A layer of amorphous silicon is then deposited on top of the titanium oxide dielectric to complete the formation of the composite interlayer. A topmost layer of a refractory metal such as tungsten is then applied over the amorphous silicon to form the topmost electrode of the antifuse.

Abstract: A fiber optic canister (14) is tested by drawing an optical fiber (12) from a generally cylincrical bobbin (16) upon which is is wound, in a direction parallel to the longitudinal axis (18) of the bobbin (16). The optical fiber (12) is directed toward the drawing location (30) of the payout drive (20), and transverse vibrations in the optical fiber (12) are damped, by a guide (40) formed as a series of spaced-apart guide rings (42) having their centers aligned along a common axis (50) that is preferably coincident with the axis (18) of the bobbin (16). The guide rings (42) have central apertures (44) that decrease in diameter from the guide rings (42) nearest the canister (14) toward the payout drive (20), defining a converging locus (36) for the optical fiber (12) as it travels from the bobbin (16) to the payout drive (20).

Abstract: A drawing machine having a drawing zone (8) for drawing silvers (2), and a plurality of flyers (14) for winding the silvers on to bobbins (16), is made compact by arranging the flyers substantially longitudinally of the paths of the silvers through the drawing zone, e.g. in echelon formation with respect to the silver paths.

Abstract: In a stranding machine system with a single lay and take up device for the rope a take up coil (5) is provided and a single lay rotor (7) which rotates and encompasses the take up coil are coaxially disposed. The take up coil and the single lay rotor are moveable reciprocally relative to each other for generating a lay stroke for the rope in an axial direction and the rope is fed from the longitudinal axis of the single lay rotor along the same to the take up coil. For taking up a difference of the speeds is generated for the take up coil and the single lay rotor depending from the given obtained take up diameter of the take up coil. The take up coil with the nominal speed and the single lay rotor for generating the required speed for the differential speed are separately rotatably driven. Thereby, the take up roller may be mounted stationary free floating in axial direction and the single lay hollow rotor member may also be free floating mounted but reciprocally driven in axial direction.

The portion of the strand extending between a removed reel and a laying roller is automatically cut and held by a gripping and severing device. Upon the loading of an empty reel into the carrier, the leading free end portion of the wire or strand is automatically clamped to the outside surface of a reel flange and brought over the rim of the flange prior to a winding operation.

Abstract: A yarn spinner has two spaced apart upstanding posts whose upper ends each have a slot for receiving and journalling opposite ends of a spindle shaft. A flyer formed by a wire constituting a guide has a loop formed in it through which spun yarn is diverted to a distributor. The distributor is a v-shaped spring clip having a hole in each side for passing over the guide wire and a ring is suspended in the apex of the V through which the yarn is threaded for diverting it to a bobbin on the spindle. Pressing the sides of the spring clip toward each other releases it for movement on the guide wire and releasing the sides re-engages it with the wire. A tensioner line running over the bobbin has a rubber band in it and a capstan allows winding and unwinding line to increase and decrease the stretch of the rubber band to corresponding change the frictional drag on the bobbin.

Abstract: A level wind spinning wheel has an improved flyer assembly wherein a level wind mechanism is incorporated in one arm of the flyer in such a way that the arm is free at one end for direct drive and axial removal of the bobbin. The arm comprises a rigid hollow tube extending parallel to the flyer spindle and having a cross-threaded journaled rod for rotation in its ends. A proximal end of the tube is supportingly connected to the spindle via a transverse member, which carries a gear train for rotating the rod. A traveler mounted on the rod carries an eye which protrudes through a lengthwise slot in the tube. A bobbin received on the spindle has a first gear which drives, through the gear train, a second gear mounted concentrically on the rod within the proximal end of the tube. The tube encloses and supports the cross-threaded rod and second gear. The slot retains the traveler eye against rotation on the rod as the traveler moves back and forth along the rod to uniformly wind yarn onto the bobbin.

Abstract: An apparatus for twisting and winding strand onto a rotating bobbin comprises a spindle located within an open top pot both mounted for coincident rotation about a common axis. A strand guide mounted on the wall of the pot guides strand from an external source to be twisted and wound onto the bobbin. During rotation of the bobbin and pot, the pot is axially reciprocated relative to the bobbin to layer the strand while strand tension is monitored by a transducer located in the strand supply path. Strand tension is controlled by controlling the differential between the speeds of rotation of the bobbin and pot in response to the output of the transducer and a reference, as taught in my U.S. Pat. No. 4,128,988.

Abstract: Prior to doffing a bobbin package, the roving is severed to form a beard which is located adjacent a stop on the spindle. After the bobbin package is doffed, the beard is located adjacent to an axial stop on the spindle. When a fresh tube is donned, the roving beard is brushed down by the tube and clamped by the bottom of the tube against the axial stop. A new package can then be wound while the roving beard remains clamped.

A permanent magnet mounted upon the collar yieldably fixes the position thereof upon the flyer arm, which carries an elongated strip of material to which the magnet is attracted, until moved by the operator.

Abstract: Disclosed is a spooling apparatus that can be threaded on the fly to anchor, controllably twist and wind filament onto a receiving spool. A receiving spool is non-rotatably mounted on a spool shaft for axial reciprocation. A lead-in pulley, whose rotational axis is perpendicular to the receiving spool axis, is spaced axially outboard with respect to the receiving spool. A flier is mounted to rotate concentrically about the receiving spool and presents a pick-up head adapted to engage the feed run of the filament as it passes between the lead-in pulley and an orienting pulley located in proximity to the inboard end of the receiving spool. The orienting pulley is canted such that the tailing run of the filament cannot be engaged by the pick-up head as it rotates with the flier although the canting of the orienting pulley disposes the feed run such that it will be engaged by the rotating pick-up head when the spool reaches a predetermined position along its range of axial reciprocation.
